# Specify the source interface for the tunnel interface as VLAN-interface 100.
[SwitchB-Tunnel0] source vlan-interface 100
# Specify the destination address for the tunnel interface as the IP address of VLAN-interface 100
of Switch A.

# Configure a static route destined for IPv6 network 1 through tunnel 0 on Switch B.

Verifying the configuration
# Use the display ipv6 interface command to view tunnel interface status on Switch A and Switch B. The
output shows that the interface tunnel 0 is up. (Details not shown.)
# Switch B and Switch A can ping the IPv6 address of VLAN-interface 101 of each other. For example,
ping the IPv6 address of VLAN-interface 101 of Switch B from Switch A.

Configuring a 6to4 tunnel

Follow these guidelines when you configure a 6to4 tunnel:
You do not need to configure a destination address for a 6to4 tunnel, because the destination IPv4
•
address is embedded in the 6to4 IPv6 address.
Because automatic tunnels do not support dynamic routing, you must configure a static route
•
destined for the destination IPv6 network if the destination IPv6 network is not in the same subnet
